Abstract:
Using Galois theory, we explicitly construct (in all complex dimensions g⩾2) an infinite family of simple g-dimensional complex tori T that enjoy the following properties:
∙ the Picard number of T is 0; in particular, the algebraic dimension of T is 0;
∙ if T∨ is the dual of T, then Hom(T,T∨)={0};
∙ the automorphism group Aut(T) of T is isomorphic to {±1}×Zg−1;
∙ the endomorphism algebra End0(T) of T is a purely imaginary number field of degree 2g.
